Acorn Atom - Released - 1980
3-D Noughts and Crosses is an adaptation of the board game Qubic which is commonly known as 3D Tic-Tac-Toe. The game plays like the original pencil game Tic-Tac-Toe but adds an extra dimension. Despite the title this version does not render the graphics in 3D, but has the four boards placed side by side. The concept is still the same, though, with the player needing to get four in a row either on a single board, vertically in a column or diagonally through the boards. It is played against an AI opponent whose level can be selected from one to five. The game is entirely played by entering coordinates with the keyboard.
